"However, when he arrived and was taken out of the crate, he collapsed to the ground, weak and dehydrated," Keren Or, a zoologist for the Safari Park, told The Dodo.

It turned out that Adam had a life-threatening birth defect that hadn't been spotted - his urethra wasn't properly connected, and his body couldn't process fluids correctly. Adam had to have emergency surgery to save his life.

To help him integrate with the park's herd of African donkeys, they had to keep their distance from the little donkey. But he quickly adjusted, and his introduction into the herd went relatively smoothly.

"Benchy [the dominant female] chased Adam for quite a while, but eventually after pushing him into one of the corners of the yard and sniffing him, she continued on her way and left him alone," Or told The Dodo.
